NetBackup 3.4.2
Solaris 2.6
Separate master and media server

All of a sudden backups were failing on this media server with the error 
"Unable to allocate new media, storage unit has none available".  After some 
investigation it was found:

1.  The robot definition was gone from the media server.
2.  The drives were renamed and the paths were switched around.  Also the 4mm 
drive on the server was now defined. And the 4mm drive on the master was now 
defined even though it strictly controls the robots.
3.  The volume host was changed from the master server to the local media 
server.
4.  The barcode rules changed the default pool from scratch back to netbackup.

And I think that was all.  Anybody have any idea what might have caused this?  
Nobody was fooling with NetBackup at the time this happened.

thanx,
dale
